About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-30S
The AirTAC SAIJ32X100-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 100 mm stroke that can be fine-tuned down by up to 30 mm, yielding a usable travel window of 70-100 mm. In the 32 mm bore class, it delivers 402 N of push force at 0.5 MPa and 563 N at 0.7 MPa, making it well-suited for lighter-duty precision tasks.
This variant includes a magnet for position sensing and uses a PT tapered port thread. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to set the travel end and does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-30S Is Used
Product Changeovers
Dial in the 70-100 mm stroke window during format changes on a packaging line, avoiding the need to physically swap out cylinders for different part sizes.
End-Stop Calibration
Fine-tune the final retract position during machine commissioning to achieve exact placement without adding bulky external stopper hardware.
Sensor Mapping
Leverage the built-in magnet and dual sensor grooves to easily mount CMSE or DMSE switches for precise position feedback in automated assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-30S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and on-the-fly end-position tuning without swapping cylinders. If your setup demands less force, stepping down is not an option in this series, but if you need significantly more thrust, a 40 mm bore provides 628 N at 0.5 MPa. The adjustable 70-100 mm window is perfect for machine changeovers where product sizes vary slightly.
Because this is a 100 mm stroke, side-load risks are minimal, but always ensure the load is guided externally. Remember that the rear stopper only trims the retract position; it will not hold the load safely without continuous air pressure. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. This SAIJ model uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-30S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 70 to 100 mm, letting you set the exact end position at commissioning without replacing the cylinder.
